Sleeve Bearing
Sleeve bearings offer an economical solution due to their simple, low-cost design. They use lubricating oil to reduce friction and ensure quiet performance when new. However, these bearings wear down faster than ball bearings, limiting their long-term durability. Over time, the oil slowly evaporates through the seal, and dust can work its way into the bearing, which slows down the fan and makes it noisier. In extreme cases, uneven wear may cause the fan to become unbalanced, creating strong vibrations. Maintenance typically requires either removing the seal to add fresh oil or performing a full fan replacement to restore proper operation.

Hydraulic Bearing
The hydraulic bearing represents an advancement of traditional sleeve bearing designs. While maintaining the core structure of a sleeve bearing, it incorporates an enlarged oil reservoir and an integrated oil recirculation system. These enhancements enable two key performance improvements: extended service life and significantly reduced operational noise compared to conventional sleeve bearings.
Though fundamentally a sleeve bearing variant, the hydraulic design has become a common feature in WINSINN cooling fans. It’s important to note that while hydraulic bearings are widely implemented across WINSINN's product line, they’re not employed in every fan model within the brand’s catalog.

Dual Ball Bearing
Dual ball bearings represent an advanced rolling-element bearing design. This configuration utilizes two precision ball bearings, each containing multiple small steel balls that orbit the shaft axis. During operation, the inner race and balls rotate synchronously with the fan shaft assembly. The spherical geometry of the rolling elements inherently minimizes friction while eliminating lubrication leakage risks.
The encapsulated design fully integrates the bearing system within the fan housing, creating a protected operational environment isolated from external contaminants. This sealed architecture contributes to exceptional bearing longevity, typically exceeding 50,000 hours of continuous service, with demonstrated resistance to wear and degradation - particularly advantageous for high-RPM applications.

FCC, CE, RoHS
All WINSINN cooling fans comply with FCC, CE, and RoHS certification standards. The product line features three bearing configurations with differentiated service durations: sleeve bearing and hydraulic bearing models come with 1-year included support, while dual ball bearing systems offer 5-year extended service coverage.

Customers find the fan works well as a drop-in replacement for 24V 3D printers and appreciate its value for money. The noise level receives mixed feedback - while some find it super quiet, others report horrible grinding noise. The air flow and cooling performance also get mixed reviews, with some saying it moves a lot of air while others say it doesn't move enough, and while some find it good for cooling the hot end, others report overheating issues. The longevity is concerning, with customers noting that bearings fail within a year.

- Reviewed in the United States on February 7, 2024Style: 5V - 5000RPMVerified PurchaseThese 40mm 5V fans come in a nice plastic case. The small 40mm 5V fans are very useful for smaller projects with MCUs, Raspberry Pis or MOSFETs involved so it's worth picking up a 5 pack. At about 2 bucks each, they're a pretty good value too. Running them at 60% PWM seems to be more than adequate cooling and also keeps them in a nice and quiet zone; when running them at full blast they do output quite a bit of air but also become high pitched and annoying.

- Reviewed in the United States on November 24, 2018Style: 24V - 5000RPMVerified PurchaseI purchased these to replace the noisy fan on the heat sink for my Monoprice Select Plus IIIP printer (same as the Wanhao Duplicator i3 Plus). The original fan was noisy from the day I received my printer and it eventually died a few days ago. The new fan is incredibly quite. In fact, after I installed it, I had to actually look at it to see if it was turning. Once the fan is at full speed, you can hear it running but it is still much, much quieter than the original.
I have noticed two issues with using this as a replacement on my printer:
First, the lead length is much longer. The original fan lead was 80mm (3.14 inch) long. These fans have 290mm (11.4 inch) long leads (see pictures). I ended up bundling the extra length up inside the housing on the back near where the connector plugs in.
Second, as others have pointed out, these fans take a few seconds to get up to full speed. I don't consider this a significant issue, especially in my use case where it is on constantly while the printer is on.
Replacement fans are $8 each from monoprice (plus shipping) so I figured getting five for basically the price of one was a great deal. Even if they don't last as long as the original, they are quieter and cheaper than the replacement fans from monoprice. And, bonus, I automatically have some spares on hand if one goes out.

- Reviewed in the United States on October 7, 2023Style: 24V - 5000RPMVerified PurchaseI run a 3D printing business and gone through about every 4010 fan you can buy. I've found that these are the best value you can get for a fan on Amazon. They only last a couple months at 24/7 operation but at ~$2 each you can't beat the price with the quick delivery. All the "higher quality" and more expensive 4010s I've tried don't last long enough to be worth the extra cost. For any hobbyist printers I'd recommend making/buying a new hotend housing to accept blower fans and ditch the 4010s entirely. These just don't last like the blower fans do. In the last 3 years, I've gone through so many 4010s I lost track of the exact number.
I am down to my last 3 of the Ender 3 Pros left in production as I transition to all Prusa machines so this is likely the last batch of fans I'll need to buy. I'd recommend everyone printing for profit big or small, just make the move to higher end machines as you can afford it so you don't have to keep buying cheap parts that don't last. It's way worth the money upfront.
- Reviewed in the United States on April 23, 2020I, like many others stuck an allen screw in to my fan on my Maker Selct v2 while I was putting it back together after removing a piece of filament after the roll ran out. When I got my printer the extruder fan would make a god awful squawking as the machine was booting up and then normalize, but was never very quiet. I bought this printer as an open box and I suspected that the noise might have been the reason that someone returned it because it was otherwise a perfectly fine printer. Needless to say, after I broke off three blades from the same side of the fan the fan was VERY noisy and rattled anything that wasn't secure in it's wake.
I say all of that to qualify my review because I'm about to rave at how quiet the fan is, but it could be because I've been living with a fan that was on it's last leg for a couple of years and one that was severely damaged for a week or so.
Having said all of that, this fan is incredibly quiet. I booted the machine after replacing the fan and waiting for it to come on.... waited....must have reversed the wires on the plug when I shortened it and put it back together... NOPE it's just that quiet. Can't hear it at all. My printer sits right next to me at my desk and since we've been quarantined it's been running pretty much all day every day and it's such a better experience now that the fan isn't rattling or squawking at me. Recommend these fans if you're looking for a quieter (than mine was) replacement or if like so many of us that have these printers, have stuck an allen wrench through your fan at full speed and broken off some teeth. Eventually the imbalance will wreck the fan anyway so you might as well go ahead and order some.

The fans sometimes fail after about a year and you have to buy new ones but on the other hand they are really cheap so it's not too bad for home use. For a server you dint want to open for years you might want to spend 4x the price but if you want something cheap that will need some maintenance then these are great.
